Lori Loughlin filed for divorce in Los Angeles Superior Court on September 4, citing irreconcilable differences and listing August 31, 2025 as the separation date. The split follows the couple's guilty pleas in the 2019 Varsity Blues scandal, prison sentences, and a source telling Page Six that Giannulli used Loughlin for years.
TMZ was first to report the filing, which Page Six confirmed. The "Full House" alum, 62, married fashion designer Mossimo Giannulli, 63, on November 27, 1997. In her petition, Loughlin confirmed the couple signed a prenuptial agreement on October 28, 1997 — a month before the wedding — and amended it on August 11, 2015. She asked that properties, assets and debts be divided according to the prenup, that spousal support be determined at a later date, and that Giannulli cover her attorneys' fees and costs.
Their two daughters, Isabella Rose, 27, and Olivia Jade, 26, are adults, so custody is not at issue. The financial proceedings will center on the prenup's terms and whatever community property the court must sort through.
The divorce formalizes a split that became public in October 2025, when Loughlin's representative confirmed the couple were "living apart and taking a break from their marriage," adding that there were no legal proceedings underway at the time. Weeks later, a source close to the actress told Page Six she wanted "nothing to do with" her longtime partner. "Mossimo used Lori for years," the insider said. "She was hoping maybe he would change when he got out of prison, but he got worse." The source added that Loughlin's tipping point was allegedly discovering "incriminating" text messages and emails on Giannulli's phone.
The couple had already been unwinding their shared life: they sold their Hidden Hills mansion for a reported $12.65 million late last year.
The marriage had survived the most public crisis imaginable. In 2019, Loughlin and Giannulli were charged in the Operation Varsity Blues college admissions scandal; prosecutors accused them of paying more than $500,000 in bribes to get their daughters into the University of Southern California as crew recruits. Both pleaded guilty in 2020 — Loughlin to one count of conspiracy to commit wire and mail fraud, Giannulli to that plus honest services wire fraud. She served nearly two months in federal prison; he served nearly five.
An insider told outlets that things were never the same after weathering the scandal and the prison sentences together, with Loughlin feeling betrayed as the two drifted apart. Nearly three decades after the wedding, the marriage that endured federal prison did not survive the aftermath.
